Definitions

  • the invention relates to a method and a device for processing at least two synthetic threads running at a distance next to one another in a textile machine, the threads being passed through at least two successive processing stations, the processing surfaces of which are at an angle to one another.
  • a process for producing a bulged, drawn polymer yarn is already known (DE-AS 17 95 640), in which undrawn multifilament yarn made of a polymer is drawn in a drafting device and then twisted by false twisting is swapped.
  • the threads run continuously in the same running plane, which is determined by the processing areas, such as the circumference of the delivery rollers or godets.
  • the prior art also includes constructions in which, for example, rotating elements with axes of rotation are used which lie in mutually perpendicular planes, such as, for example, delivery rollers and godets.
  • rotating elements with axes of rotation which lie in mutually perpendicular planes, such as, for example, delivery rollers and godets.
  • the problem thus arises of also rotating the running plane of the threads running next to one another.
  • the present invention has for its object to provide a method and an apparatus of the type mentioned, which or which ensures in a simple manner that the threads in successive processing stations, the processing surfaces are at an angle to each other, run at a designated distance .
  • This object is achieved in that the threads between the processing stations are guided with a positive retention of a distance from a first running level of the processing station passed through to a second running level of the processing station to be passed.
  • This has the advantage that the running levels of threads running next to each other, e.g. bifilar running threads, the processing surfaces of the processing stations are adapted, even if these processing surfaces are at an angle to each other. In this way, the necessary joint laying of the two threads is made considerably easier and a considerable improvement in quality is also achieved.
  • the running planes of the threads lie at an angle of 90 ° to one another, the threads running next to one another being rotated in a positive manner by this angular amount.
  • At least one thread separating element in the area between two processing stations, the diameter of which corresponds to the desired spacing of the threads in this plane, the threads running over opposite sides of the thread separating element.
  • a pin for guiding a thread between two processing stations is already part of the prior art (DE-OS 19 47 452).
  • this pin serves as a guide device, which is arranged between a roller and a heating plate, over which a thread is drawn.
  • the leading edge of this guide device has a special inclination with respect to the traversing direction of the thread.
  • This known pin thus has a completely different function than the thread separating elements according to the invention.
  • the outer diameter of the thread separating element corresponds to the desired distance of the threads running side by side in the second running plane.
  • This thread separating element has a first region of constant diameter and a second region in the form of a conically tapering tip to increase the distance between two threads placed at the tip and guided to the first region and running closely next to one another on the outside diameter of the Thread separation element corresponding distance.
  • the axis of this tip is angled relative to the axis of the first area of the thread separating element; the tip of the thread separating element can have a nose.
  • a second function is assigned to it, namely separating threads running side by side at a certain distance from each other when placing a pair of threads with the aid of a suction pistol which, when gripped, detects the threads together.
  • Such a thread separating element can therefore be used advantageously not only where it is technically necessary to change the running plane, but also where it facilitates the manipulation of threads running alongside one another when pulling in.
  • the two threads can be put together on the nose in the area of the tip of the thread separating element.
  • This nose jumps e.g. one of the two threads, preferably the thread deflected by a larger angle, whereby the separation of the two threads from each other is facilitated.
  • the thread separating element is advantageously arranged in the thread path of the parallel threads of the godet.
  • At least one thread separating element can be arranged upstream of a guiding device guiding the adjacent threads or a processing station of the textile machine.
  • thread separating elements there is also the possibility according to the invention that a cross between the swirling chamber and the second pair of thread guides to the thread running direction are arranged thread separating element, which in an outer dividing area from a tip has diverging edges for each of the threads running side by side, which merge into an inner insertion area in parallel. This results in a simplification in the construction of the elements for producing a thread course lying next to one another when a pair of threads is placed on it.
  • the invention can advantageously also be used for guiding more than two threads running in parallel, at least two thread-separating elements being arranged upstream of a processing station or a guiding device.
  • the two thread separating elements can be arranged offset in relation to one another in the thread running direction and transversely thereto.
  • FIG. 1 shows a front view of a work station of a stretch winder 1 for two synthetic threads 2 and 3 to be treated bifilarly. As can be seen, the threads 2 and 3 are fed to the individual processing stations of this work station from a creel (not shown).
  • These synthetic threads 2 and 3 initially run side by side over a rod-shaped thread guide 5, which has profiles on its outer circumference for separating the threads 2 and 3.
  • the threads are guided several times around the thread guide 5 and a pressure roller 6 resting on a delivery roller 7 and run from there to a stretching pin 8.
  • the synthetic threads 2 and 3 running from the godet 9 next to one another are then passed on to a godet 12 arranged in the upper region.
  • This godet is in turn equipped with a laying roller 13.
  • the peripheral speed of the godet 12 is increased compared to the peripheral speed of the godet 9, so that the synthetic threads 2 and 3 are stretched.
  • the zone between the godets 9 and 12 forms the main delay field.
  • a heating device 11 In the area of this main drafting zone, a heating device 11 is installed, the two synthetic threads 2 and 3 passing through the heating device 11 side by side from bottom to top.
  • the upper godet 12 can either be a heating godet or an unheated godet.
  • the two synthetic threads 2 and 3 are guided via a pair of thread guides 14 and 14 'to a two-lane swirling chamber 15 and from there via a further pair of thread guides 16, 16' and 17 to a winding device with the two bobbins 18 and 19 for each of the synthetic threads 2 and 3. (For reasons of clarity, the second thread guide of the pair 17 is not shown in FIG. 1).
  • the two bifilar treated, synthetic threads 2 and 3 run side by side over wide areas in one plane, which are determined by the processing surfaces, such as the circumference of the delivery roller 7, the godets 9 and 12, of the heating surface of the heating device 11.
  • the axes of rotation of the delivery roller 7 and the stretching pin 8 lie in a plane which is perpendicular to the plane in which the axes of rotation of the laying roller 10 and the godet 9 lie.
  • the running plane of the synthetic threads 2 and 3 running next to one another is also rotated in this area between the stretching pin 8 and the godet 9.
  • a thread separating element 20 is used, with the aid of which the running plane of the two synthetic threads 2 and 3 running next to one another is rotated into the plane of the subsequent processing surface.
  • This thread separating element can e.g. a pin, a wire bracket or a divider.
  • the axis of the thread separating element 20 is perpendicular to the desired running plane of the two threads 2 and 3.
  • the diameter of the outer circumference of the thread separating element 20 corresponds to the desired distance of the two threads 2 and 3 running in parallel this level. 2 and 3 show that the thread 3 runs in front of the thread separating element 20 and the thread 2 runs behind the thread separating element 20.
  • the thread separating element 20 has two areas, namely a cylindrical first area 21 and then a second area 22 in the form of a tapered tip 22.
  • the axis of the tip 22 is approximately 45 ° to 75 ° with respect to the axis of the first region 21 of the thread separating element 20 angled.
  • the thread separating element 20 exercises with its tip 22 and its cylindrical region 21 perform a further function: when a pair of threads is placed on, this thread separating element 20 makes it easier to reload the individual processing stations while the machine is running.
  • FIG. 2 This mode of operation is shown in FIG. 2 in individual process steps:
  • a suction nozzle 23 of a suction gun not shown, is used to guide a pair of threads. 2a, the two threads 2 and 3 are sucked into the mouthpiece of the suction nozzle 23.
  • the suction nozzle is located in front of the godet 9.
  • the suction nozzle 23 is guided so that the pair of threads 2, 3 reaches the tip 22 of the thread separating element 20.
  • the two threads 2 and 3 are guided over the tip 22, separated from one another, onto the two sides of the cylindrical region 21.
  • the tip 22 according to FIGS. 10 and 11 can be provided with a nose 40. There is a recess 41 in front of the nose 40. On this thread separating element 20 designed in this way, the two threads 2 and 3 are not moved to the tip 22, but into the recess 41. Then the suction nozzle 31 according to FIGS. 10 and 11 slowly turns into Direction of arrow x led. The more deflected thread 2 jumps over the nose 40 rather than the other thread 3 and can then be guided more easily behind the thread separating element 20.
  • the suction gun is repeatedly guided around the godet 9 and the laying roller 10, the two in front of and behind the cylindrical region 21 of the thread separating element 20 threads 2 and 3 running side by side experience a parallel guidance with a constant mutual distance from one another.
  • this thread separating element 20 fulfills the further function mentioned above, namely the production of the desired distance when placing a pair of threads.
  • FIG. 3 shows the process sequence shown in FIGS. 2a to 2c in the direction of arrow B.
  • the effect of the conical tip 22 can be clearly seen, with the thread 3 on one side and the thread 2 on the other side according to FIG. 3b of the outer diameter of the cylindrical region 21 of the thread separating element 20.
  • Fig. 3c corresponds to the position according to Fig. 2c, i.e. the parallelism of the two threads 2 and 3 is established.
  • the two remaining threads 2 and 30 are in turn in the range of e.g. diagonally below the first thread separating element 20 arranged second thread separating element 20 ', where a separation between the two threads 2 and 30 is effected. This position is shown in Fig. 4c.
  • the suction nozzle 23 of the suction gun is repeatedly guided around the godet 9 and the laying roller 10 according to FIG. 4d and so the required parallelism of the three threads 2, 3 and 30 is produced in this area.
  • thread separating element 20 - separating and separating - the bi- or trifilar running synthetic threads when placing a pair of threads or trio of threads there is also the possibility of using thread separating elements of this type in other areas of the textile machine:
  • thread separating elements 25, 26 and 27 there are further thread separating elements 25, 26 and 27 in the area below the upper godet 12.
  • the thread separating element 25 is arranged between the upper godet 12 and a first pair of thread guides 14 and 14 '
  • a second Thread separating element 26 is located between this first pair of thread guides 14 and 14 'and the two-track swirl chamber 15
  • a third thread separating element 27 is arranged between this swirling chamber 15 and a further pair of thread guides 16 and 16 '.
  • the two bifilar treated threads 2 and 3 then run via a third pair of thread guides 17 and 17 'to the two bobbins 18 and 19.
  • the function of the further thread separating element 26 is analogous, in order to ensure that the two threads are correctly inserted into the two parallel grooves of the two-lane swirl chamber 15.
  • FIG. 6 A further possibility when inserting a pair of threads is shown in FIG. 6 in method steps d-f: as can be seen, behind the laying roller 13 there is a thread separating element 25.
  • the two-lane swirling chamber 15 with the two grooves 28 and 29 is followed by a differently designed thread separating element 33 , which is transverse to the thread running direction.
  • this thread separating element 33 has an outer dividing area 34 with edges running apart from a point for each of the threads running side by side and an inner insertion area with a spacing from one another lying edges 35 and 35 '. Furthermore, the upper thread guides 14 and 14 'according to FIG. 7 are open to the outside, whereas the lower thread guides 16 and 16' according to FIG. 8 are designed to be open towards the inside. Fig. 9 shows the elements of FIGS. 7 and 8 in an overall plan view. Instead of designing the thread separating element 33 in the form of a partial sheet, a wire bracket with corresponding edges can also be used.
  • the suction nozzle 23 is moved downward according to FIG. 6d and guided under the thread separating element 33 against the base of the partial sheet. This causes the two threads 2 and 3 to spread in the outer dividing area 34 until they abut the parallel edges 35 and 35 'of the inner insertion area and are therefore inevitably inserted into the grooves 28 and 29 of the swirling chamber 15.
  • the distance between the edges 35 and 35 ' is selected such that they guide the threads 2 and 3 in cooperation with the thread guides 14, 14' exactly in the two grooves 28 and 29 of the swirling chamber 15.
  • FIG. 9 shows a top view of the area of the swirling chamber 15 at the moment in which the threads 2, 3 are inserted into the two grooves 28 and 29 of the swirling chamber 15 by means of the suction gun via the partial sheet 33.
  • the suction nozzle 23 is then moved to the left until the thread 2 is embedded in the thread guide 16; by moving to the right, the thread 3 is embedded in the thread guide 16 '.
  • the other thread is held by one of the edges 35 and 35 'in a position in which it does not hinder the handling of the thread moving with the suction nozzle.
  • the two thread separating elements 26 and 27 according to FIG. 5 can be omitted, whereby nevertheless a perfectly functional positioning of the two threads 2 and 3 running next to one another in the thread guides or respectively further processing stations is guaranteed.
  • the running plane of the e.g. bifilar threads 2 and 3 are rotated, the special design of the thread separating element or elements also simplifying the placement of a pair of threads or trio of threads.
  • the invention is e.g. applicable to stretch texturing machines with bifilar threads.
  • the use of such thread separating elements is not limited to a draw texturing machine, but can also be used on draw twine or draw winder without texturing or on machines with a different type of texturing, such as false twist.
